LT3466EDD-1#TRPBF

LED Driver IC Overview

The LT3466EDD-1#TRPBF is a dual white LED driver and boost converter in a 3x3 DFN package. It operates from an input voltage range of 2.7V to 24V, delivering up to 300mA per channel with two independent outputs. The device features a fixed 2MHz switching frequency and supports PWM dimming for brightness control. It includes built-in Schottky diodes and provides open-circuit protection by limiting output voltage to 42V. Operating temperature ranges from -40°C to +85°C.

LED Driver IC Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm pinout and functional configuration. Ensure the ordering code matches the specific variant required for your application, as minor suffix differences may indicate different packaging or temperature grades. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards and RoHS compliance requirements.

LED Driver IC Selection Notes

Select this component when designing circuits requiring dual independent LED channels from a single wide-input voltage source. The fixed 2MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 300mA output limit per channel when sizing LED strings. The integrated Schottky diodes are advantageous for space-constrained designs where minimizing external parts is critical for board real estate.
